Roughly 15 percent of the 70,000 fans would arrive to stadium via subway, light rail, bus or another form of transit, according to AEG's estimates.

The traffic analysis was revealed in AEG's environmental impact report on the $1.2 billion project.

The stadium would serve as the home for one or two National Football League teams. NFL teams typically play eight home regular season games a year, as well as a handful of exhibition games.

But the stadium is also expected to host other events, such as rodeo shows, soccer matches and wrestling shows, according to the report.

To determine the impact of traffic in the area, AEG studied three scenarios: A Saturday daytime event, Sunday afternoon football game and Monday night football game.

AEG estimates that 20 percent of patrons would use transit on a weekday and 15 percent on a weekend. Approximately 7 percent of spectators would walk-in for a weekday event, according to the report and 3.5 percent would walk-in on a weekend event.

But the vast majority would drive. To ease traffic, AEG is proposing a three-pronged approach: Encourage mass transit, use smartphone technology to provide information about and access to parking, and widen streets, sidewalks, and freeway ramps.

The draft environmental impact report is being circulated for a 45-day public comment period. AEG hopes to have the City Council sign off by the end of the summer.
